The Paper Napkin email rejection service: "That's where Paper Napkin comes in. Give them email@example.com (or paamail.com, to be less suspicious), tell them it's your address, and when they write you, they'll automatically get a response telling them how badly they've been rejected. If they sound desperate enough, it may even get posted and ridiculed. Yes, it's cruel, so use it wisely."
The rejection blog as an rss feed.
